Seedling
2-3 weeksTiny seedlings with first true leaves appearing; very fragile with minimal root development
Keep soil lightly moist but not wet; provide bright light; avoid overwatering which causes damping off; thin seedlings to proper spacing early
Vegetative
3-6 weeksYoung plants developing bushy growth with multiple stems and small, aromatic leaves; plant becomes more compact and dense
Reduce watering as plant establishes; pinch growing tips to encourage bushiness; begin light harvesting of leaves; ensure excellent drainage
Flowering
6-8 weeksPlant produces delicate flowers in shades of purple, lavender, or pink arranged in small whorls along stems; foliage remains compact and aromatic
Continue minimal watering; deadhead spent flowers to encourage more blooms or allow flowering for ornamental appeal; flowers attract pollinators
Maturity
Perennial; continues indefinitelyFully established plant with dense, mounding growth habit; flowers and foliage at peak development; strong minty aroma when leaves are brushed
Harvest regularly to maintain shape and vigor; prune back in late summer to encourage new growth; extremely drought-tolerant at this stage
Dormancy/Winter
2-4 months depending on regionPlant growth slows or stops in winter; foliage may thin in cold desert regions; survives cold better than tropical mints
Minimal or no watering; no fertilizer needed; cut back dead growth in early spring before new growth emerges; protect from extreme cold in zone 8
